A person who has recovered from COVID-19 takes part in a rehabilitation programme in Genoa, Italy. The lung scans were the first sign of trouble. In the early weeks of the coronavirus pandemic, clinical radiologist Ali Gholamrezanezhad began to notice that some people who had cleared their COVID-19 infection still had distinct signs of damage....
by American College of Physicians COVID-19 is spread most often through respiratory droplets or aerosols and little evidence exists supporting transmission through surfaces. As such, social distance and proper ventilation are key determinants of transmission risk. Findings from a review of published research, articles, and reports is published in Annals of Internal Medicine. Researchers from Montefiore Medical...
By Dr. Liji Thomas, MD,Sep 14 2020 The frequency of children carrying asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been suggested to be higher than among adults. It is also suggested that asymptomatic children enhance viral spread. A research letter by published in the journal JAMA Pediatrics in September 2020 explores the truth of...
ELIFE West Nile virus spreads most efficiently in the US at temperatures between 24-25 degrees Celsius (75.2-77 degrees Fahrenheit), a new study published today in eLife shows. The results suggest that climate change could lead to the increased spread of West Nile virus in some places, while potentially causing a decrease in others, and provide insight on...
EUROPEAN LUNG FOUNDATION IMAGE: CT SCAN OF PATIENT’S LUNGS SHOWING COVID-19 DAMAGE IN RED. COVID-19 patients can suffer long-term lung and heart damage but, for many, this tends to improve over time, according to the first, prospective follow-up of patients infected with the coronavirus, presented at the European Respiratory Society International Congress. [1] Researchers in...

Credit: Wikipedia/CC BY-SA 3.0 As the flu season approaches, a strained public health system may have a surprising ally—the common cold virus. Rhinovirus, the most frequent cause of common colds, can prevent the flu virus from infecting airways by jumpstarting the body’s antiviral...
52 per cent of children with virus do not show most common symptoms in adults They tend to skip meals, suffer headaches and feel exhausted, scientists found And one in six school-aged children break out in skin rashes that are very itchy By CONNOR BOYD If your child brings home an uneaten packed lunch it...
An international team of researchers studied coronavirus in lab grown brain ‘organoids’ and mouse brains They found clear evidence that the virus can take over brain cell machinery to make copies of itself Brain cells near the infected ones were oxygen-deprived and dying Studies suggest that anywhere from 30 to 84 percent of COVID-19 patients...
By Dr. Sanchari Sinha Dutta, Ph.D.Sep 8 2020 A recent study demonstrates that functional CD4+ and CD8+ T cells specifically targeting the entire proteome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain active in individuals who have recovered from severe or mild coronavirus disease 2019 (COVID-19). Moreover, the magnitude of T cell response is correlated with the...
By Sally Robertson, B.Sc. Researchers at the University of Washington in Seattle have conducted a study suggesting that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can directly infect heart tissue and contribute to whole-organ cardiac dysfunction. Charles Murry and colleagues found that the virus directly infected cardiomyocytes, impaired their electrophysiological and contractile properties,...
